Marsh, James, a Dublin physician and chemist, who distinguished himself by the discovery of a process by which the most minute portions of arsenic can be detected in any body or liquid, was born in 1789. His discovery was given to the world in the Edinburgh Philosophical Journal for October 1836. The process, details of which will be found in the Encyclopaedia Britannica, is constantly made use of in medical jurisprudence.
